Title: Brush wear quantity confirming device for motor and motor provided with the device
Inventor: MORIMOTO YOSHIHIRO
IPC: H02K13/00
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To assure enhanced stability of operation with a simplified structure by providing a holding means for holding, to be slidable in the forward and backward directions, a detecting means of which front end side is located at the side surface side of brush in the electric motor, while the rear end side is projected to the outside of the motor. SOLUTION: A holding means 1 holds a detecting means 2 which is formed like a round rod to be slidable in the axial direction, while a coil spring 11 allows the sending means 2 to be inserted slidably in the axial direction of the coil. Upon the receipt of the effect of coil spring 11, the detecting means 2 allows, under the condition that a stopper member 10 is placed in contact with the end part of a sliding regulating hole 9, the front end portion 12 of the stopper 10 to be projected in an adequate length from a through-hole 3, while the rear end portion 13 to be located at the open end of the through-hole 3. Therefore, the amount of brush wear of motor can be easily assumed from the amount of projection of end portion by checking or contact with the end portion of the detecting means through the sliding to the brush side of detecting means and thereby the replacing period of brush can be accurately and quickly known and stable operation can also be attained with a simplified structure.

Abstract: PURPOSE:To facilitate the level switching of a resistance attenuator by generating a level selection signal according to the input of a key signal from a keyboard. CONSTITUTION:When key operation for inputting a code for setting the attenuation level of the resistance resistor 14 is performed with push type keys 11, a CPU 12 generates the level selection signal, which is inputted to a level switch 15; and then the level switch 15 makes a specified changeover contact and breaks other changeover contacts, thus setting the attenuation level of the resistance attenuator 14.

Title: Combustion control method of incinerator and apparatus therefor
Inventor: SUZUKI TOMIO
IPC: F23G5/50
Filed: 1990-05-16
Abstract: PURPOSE:To attain combustion with less environmental pollution and no avail by a method wherein the radiant heat generated by the flame in an incineration furnace is detected to monitor the combustion state in the incineration furnace directly, and combustion air is controlled according to the fluctuation in the detected results so as to restrain generation of carbon monoxides and black smoke. CONSTITUTION:In the case a radiant heat ratio B/A is less than 1.2, where A is the radiant heat detected at present and B is the radiant heat detected a specified time period ago, it is decided that the fluctuation in the radiant heat is within a specified range, and combustion air for complete combustion is not fed. And, in the case the radiant ration B/A is not less than 1.2, it is decided that a sharp fluctuation in the radiant heat occurs, and an air flow rate corresponding to the ratio is set. Since the combustion state in a combustion chamber 14 is directly monitored by an optical detector 26, even when a sharp increase in the heat generation amount in the combustion chamber 14 arises, it is instantaneously detected by the optical detector 26. A combustion controller 40 receives signals from the optical detector and outputs control signals to a flow control valve 38 so that combustion air for complete combustion is supplied into combustion gas via a combustion air feed device to completely burn unburnt components.

IPC: B21D43/00
Filed: 1995-05-26
Abstract: PURPOSE: To form a through hole in a high precision by making the rigidity of a first supporting arm lower than the rigidity of a second supporting arm and making the interval between both arms high near the connecting part. CONSTITUTION: A hollow square member guide member 4 and a punch guide 6 are provided on a base table 2. Further, the steel-made first supporting arm 22 extending toward the rear part is provided on the base table 2 and a connecting member for supporting the steel-made second supporting arm 24 is fitted to the rear end thereof. The rigidity of the second supporting arm 24 is high and the hollow square member P can be inserted while keeping straight line state. The first supporting arm 22 has the comparatively low rigidity and is bent into arch-shape, but horizontally and rockingly supports the seconds supporting arm 24 and an inner die 30. Large shock and fastened engagement between a punch 10 and the inner die 30 are prevented by vertically rocking the inner die 30.  In this case, the interval between the first supporting arm 22 and the second supporting arm 24 is made large near the connecting part in comparison with near the base table 2. By this method, even in the surface containing the seam connecting part, the through hole having a prescribed shape size can be formed in high precision.

IPC: G01V8/12
Filed: 1988-05-25
Abstract: PURPOSE:To maintain high human body detection accuracy, and also, to shorten a detection time by setting the detection time in accordance with a variation state in a detection area. CONSTITUTION:First of all, by a whole area detection control means 21, a scanning means 20 is controlled so that a condensing range of infrared rays extends over the whole area of a detection area 1a. When a human body operation exists in the detection area 1a, a variation of the light quantity of infrared rays is detected 4, and based on the variation of the light quantity, existence of the human body is detected by a human body detecting means 12. Subsequently, based on the human body detection frequency from the human body detecting means 12, the frequency is calculated by a frequency arithmetic means 22, and a human body detection time of each of each partial area A1-B7 is set by a detection time setting means 23. In that case, the more the human body detection frequency in the detection area 1a is, the shorter the time for detecting the human body of each of each partial area A1-B7 is set, therefore, the human body can be detected with high accuracy and quickly, and also, the detection time can be shortened.

IPC: H04L7/033
Filed: 1977-10-25
Abstract: PURPOSE:To obtain the necessary pulse with no adjustment regardless of the clock frequency as well as to facilitate the IC formation, by leading out the optimum phase pulse for retiming from the clock pulse of the reception side unit. CONSTITUTION:Timing supply unit 1 supplies the clock pulses of the same frequency repetitively to transmission side unit 2 and reception side unit 3 each. Transmission circuit 5 performs the code conversion via the pulse supplied to unit 2 and transmits the signal to the intra-office transmission line. Reception circuit 6 demodulates the signal to supply it to unit 3. At unit 3, pulses 9-12 of different phases are produced via the clock pulse. And the occupation rate of each pulse is about 0.5 when the intervals between the pulses are equal to each other. In this case, each of pulses 9-12 whose phases are shifted about 90 deg. each other is ratched to the levels of 4 units of the pulse, and the level at that moment is decoded to select the optimum phase of the clock pulse.

Title: Wire-cut electric discharge machining
Inventor: KINOSHITA MITSUO
IPC: B23H7/20
Filed: 1982-07-22
Abstract: PURPOSE:To perform second cut and machining at plural points automatically, by storing the working path in a memory while returning from the work-end point to the work-start point contrarily from the machining operation. CONSTITUTION:When performing second-cut machining or machining at plural points through wire-cut discharge machining, a wire electrode is cut and stretched again in the machining start hole. Here the machining path is stored in a memory without cutting the wire electrode and upon reaching to the end point of machining, the memory is called to move the wire electrode contrarily from the machining operation to return to the machining start point WCH. Consequently if second cut machining or plural machining is performed from the start point of machining; other machining can be continued automatically.
